In this special book club episode of 'The Mathematicians Podcast', I sit down with author, maths communicator, and museum learning consultant, Thomas K. Briggs. Join us for a glass of wine and a deep dive into Tom's book, 'The Mathematicians Library', a title so intriguing it was a must-have for the show.

This 'Injectives' sub-series episode is a one-to-one conversation; today exploring the vast history of mathematical literature. Discover the oldest book in Tom's personal collection and unravel the criteria for what truly constitutes a "book of mathematics". Tom paints a vivid picture of ancient mathematical works, describing the evolution of writing media before the age of flat sheets and ink.

The discussion navigates through the emergence of authorship in the Mediterranean, Indian, and Chinese traditions, and Tom shares his favourite example of a significant mathematical work without a known author. He also recounts the fascinating journey of a particular mathematical text through the ages, a story of translation and transcription that has preserved ancient knowledge.

In a new segment of "Desert Island Codex," Tom reveals which ancient mathematical document he would choose to study in solitude and which ancient lecture he would love to have heard.

Moving beyond the book, the episode looks into Tom's work as a museum consultant. He sheds light on the origins of encryption and the methods ancient leaders used to send secret messages. The discussion also explores the vast, untranslated collection of Babylonian tablets and what they might still reveal about Mesopotamian mathematical understanding.

Finally, Tom offers his own insightful, pithy definition of what mathematics truly is. He also reveals which mathematician he is most excited to see featured on a future episode of the podcast.

Tune in for a captivating conversation that journeys through the annals of mathematical history, from ancient texts to modern museum exhibits.

In this episode of The Mathematicians Podcast, I am jumping ahead 800 years and travelling 5,000 km back to India to pick up the threads of a fascinating mathematical tradition. I’ll be introducing you to Umaswati, a pivotal figure from around the 2nd Century CE who helped systematise the teachings of Jainism, a religion where "Right Knowledge" and the study of the cosmos made maths a fundamental pursuit.

Together, we explore the four broad periods of Indian religious development: Vedic, Śhramana, Puranic, and Bhakti, and see how the Jain tradition carved out a unique space for mathematical inquiry. We’ll discuss:

• The approximation of \pi : Why the Jains used \sqrt{10} and how they handled circular segments.

• The power of place value: How ancient Indian poets and scholars were comfortably using numbers as large as 10^64 while the Greeks were still stuck at the Myriad

• The Five Types of Infinity: Long before Georg Cantor revolutionised set theory in the 19th century, Umaswati and the Jain scholars were already classifying different scales of the infinite and the transfinite.

Join me as I navigate the intersection of faith, philosophy, and the infinite.

When is an approximation "good enough"? This week on The Mathematicians Podcast, host Benjamin Cornish opens the doors to his gem and fossil shop to discuss why a polished piece of glass, or a clever mathematical shortcut, can sometimes be just as effective as the real thing.

We are shifting our focus toward the sprawling, shifting history of Mesopotamia. Today, we tackle a double bill of Babylonian titans: Nabu-rimanni and Kidinu. Though separated by two centuries and a revolving door of empires (from the Persians to the Greeks), these two temple astronomers foresaw the blossoming of predictive science.

In this episode, we explore:

• The "Feet of Clay" History: A whirlwind tour of Babylon, from the Tower of Babel and Hammurabi’s Code to the rise of the Persians and the lightning conquest of Alexander the Great.

• System A vs. System B: How Nabu-rimanni’s constant velocity model evolved into Kidinu’s sophisticated "zigzag" acceleration system.

• The Two-Second Error: How ancient mathematicians using little more than water clocks calculated the synodic month with a precision that rivals modern satellite data.

• The Babylonian Legacy: Why the Greeks (including Hipparchus) owe their greatest discoveries to the meticulous clay tablets of the East.
